Instinctual Stacking: So/Sp

Notes:

• His mental illness ties in with the Unhealthy Level (8) of Type 6: “They see conspiracies plotted against them everywhere; they feel persecuted by everyone, especially by authority figures who, they are convinced, are trying to punish them for their failures. (…) Mere suspiciousness has deteriorated into true craziness – insane paranoid delusions. Paranoid delusions of persecution may alternate with compensating delusions of grandeur and delusions of reference, the notion that they are being watched by someone important – God or the ghost of a childhood hero, for example – providing neurotic Sixes with a sense of importance.”
